Title: Improvements relating to fuel injection pumps for diesel engines
IPC: F02D1/00
Filed: 1969-09-03
Abstract: 1277493 Fuel injection pumps ROBERT BOSCH GmbH 3 Sept 1969 [4 Sept 1968] 43605/69 Heading F1A The delivery quantity regulating member 2 of a fuel injection pump 1 is returned to its zero delivery position by means of an hydraulically actuated adjusting means 9, the actuating pressure of which is controlled by a magnetically actuated spool 22. To start the engine a switch 27 is moved to position IV wherein a starter 29, pre-heater 28, feedpump 16 and electromagnets 4 and 23 are actuated, the latter causing a bar 3 and spool 22 to move in the direction of arrows 3a and 22a. Movement of the spool releases pressure in the adjusting means 9 and the member 2 moves freely until a cut out 2a on the member abuts bar 3; in this position excess fuel is delivered. For normal running the switch is returned to position II wherein the spool is unaffected, but bar 3 is returned to its normal position to prevent further excess fuel delivery. On returning the switch to position I magnet 23 is de-activated and pressure build up in the adjusting means returns the member 2 to its zero delivery position. The normal running position of the regulating member 2 is determined by a governor coupled to the driven engine. (For Figure see next page)

Abstract: 967,068. Viewfinders: focusing devices. SOC. D'OPTIQUE ET DE MECANIQUE DE HAUTE PRECISION. Dec. 21, 1960 [Dec. 21, 1959], No. 43882/60. Headings G2A and G2J. A combined view finder and focusing device comprises a transparent optical element having a first plane face carrying a plurality of similarly dimensioned protrusions, the protrusions having plane faces which intersect to form ridges or apices having their vertices and bases lying in two parallel planes, means for varying the position of the objective relation to the element to locate an image between said two planes, and an eyepiece for viewing the image, the arrangement being such that, in use of the device when an image formed by the objective is located between said two planes the image is seen at maximum definition, but if the image is moved away from such location, the image is seen as being blurred. As shown (Fig. 1), a combined viewfinder and focusing device comprises an objective 1 slidably mounted in a tube 3, a semi or fully reflecting mirror 5 for reflecting some or all (all in the case of a single lens reflex camera) of the light for exposing a film 4 towards a viewfinder eyepiece 8 and a transparent element 6 having a ridged face 9. In use the objective 1 is moved until the image produced thereby is between the two parallel planes containing the ridges, the end point being recognised by the replacement of a blurred image by a single sharp image. Other forms of elements 6 are illustrated in Figs. 3-5 (not shown). Fig. 6 shows a camera fitted with a device according to the invention, in which camera light passes through an afocal lens system 13, 14 and objective lenses 15, 16 to expose a film 12. Silvered patches 10, 11 formed in the plane common to prisms 17, 18 reflect light to the viewfinder and focusing device 1, 6, 8, 9. The patches are of such area and so positioned that they form a single image in the image plane of the eyepiece 8 of area less than that of the pupil of an observer's eye 7.

Abstract: 1492465 Etching INTERNATIONAL BUSINESS MACHINES CORP 27 Oct 1975 [31 Dec 1974] 43.997/75 Heading B6J  A process for producing a nozzle includes forming a P<SP>+</SP> layer on one surface of a section of non-P<SP>+</SP> crystallographically oriented monocrystalline silicon and anisotropically etching a tunnel from the opposite side of the section until the etching is terminated by reaching the P<SP>+</SP> layer on the said one surface if no P<SP>+</SP> layer is present at that point. As shown in Fig. 9 a nozzle has been formed by producing a P<SP>+</SP> layer 29 in a silicon section 27 and subsequently growing or depositing a film of silicon dioxide or nitride 35. A tunnel 31 is subsequently etched, the etching terminating when the P<SP>+</SP> layer 29 is reached. Apertures 39 are then produced. Alternatively, as in Fig. 4, the P<SP>+</SP> layer 15 has been prevented from completely covering one surface of the silicon section 1 by selective masking with silicon nitride 7 and silicon dioxide 9. Thus the anisotropic etching proceeds through to the said one surface. The anisotropic etchant may be aqueous sodium hydroxide or aqueous potassium hydroxide or hydrazine-water or pyrocatechol, ethylene diamine and water or aqueous mixture of potassium hydroxide and n-propanol. The P<SP>+</SP> layer preferably has a p-type dopant concentration greater than or equal to 7 x 10<SP>19</SP> cm<SP>-3</SP>.

Title: New assay technique
Inventor: FINTER NORMAN BOYNE
IPC: G01N33/68
Filed: 1962-11-23
Abstract: Interferon is estimated by (1) adding said interferon to living cells, (2) adding a haemadsorbing virus, (3) incubating, (4) adding a suspension of red blood cells to effect haemadsorption (5) liberating the haemoglobin in the haemadsorbed cells and (6) estimating the liberated haemoglobin colorimetrically or chemically.  Suitable living cells are calf, rabbit, monkey or chick embryo kidney cells or human cell strains; the haemadsorbing virus may be an influenza or para-influenza (myxovirus) or Semliki Forest virus; and the red blood cells may be of guinea pig, chicken, goose or monkey and may be in suspension in a saline medium comprising calcium and magnesium ions. In an example calf kidney cell sheets are prepared by the initial use of trypsin to give a suspension; interferon is produced by the action of influenza A virus on calf kidney tissue cultures, the virus being subsequently rendered inactive.  The interferon preparation in a specified medium is added to the cell sheets and incubated and then Sendai virus (infected allantoic fluid) is added and the mixture further incubated.  A suitable suspension of guinea pig red blood cells was added, and after haemadsorption, the cell sheets were drained and washed before being contacted with distilled water to effect haemolysis.  The amount of haemoglobin thus produced, and thus the amount of interferon which reduced the extent to which haemadsorption took place, is determined by spectrophotometry.  Virus control and cell control preparations and standard interferon preparations were used and a method of determining the result is described.  The haemoglobin (i.e. oxyhaemoglobin) may be estimated as a derivative, e.g. methaemoglobin (using alkaline potassium ferricyanide) or pyridine haemochromagen, which may be determined by known methods, or as haemoglobin itself (by reduction with sodium dithionate) which is determined spectrophotometrically, or as carboxyhaemoglobin, determined photometrically.

Title: A process for the production of potentially crimped filaments
IPC: D02G1/18
Filed: 1959-12-31
Abstract: <PICT:0939314/IV(a)/1> Potentially crimped filaments of a synthetic thermoplastic linear high polymer are made by stretching filaments of such a polymer in a continuous manner to 2-8 times their original length, and, during the stretching operation, heating the filaments on one side for a very short time by passing them at a speed of more than 100 m./min. over a small hot surface heated to 300 DEG -900 DEG C., the filaments making contact with the hot surface for a distance of 0,3-5,0 mm. and the threadline of the filaments being so deflected in passing over the hot surface that the portion of the filaments approaching the surface forms with the portion of the filaments leaving the surface an angle of 130-170 degrees. Filaments of polyethylene teraphthalate, polyhexamethylenediamine adipate and poly-S -caprolactam may be so treated.  An electrically heated wire may be used as the hot surface, which is preferably heated to 500 DEG 600 DEG C., the period of contact of the filaments therewith being 0,00008 to 0,01 secs.  Before passing the filaments over the hot surface they may be wetted with water or with an aqueous solution of a wetting agent.  Filaments so treated are crimped by shrinking, e.g. by heating in air at 100 DEG -240 DEG C. or passing them over a plate or roller at the same temperature, or by heating in water at 80 DEG -100 DEG C.  Alternatively a woven or knitted fabric may be made with the potentially crimped filaments and the fabric subjected to shrinking by treatment as above, or with a suitable solvent, e.g. ethylene chloride or acetone.  In apparatus as shown, filaments 1 are passed around feed roller 2 and separating roller 3, the stretch point being localized by passage of the filaments around heated snubbing rod 4, having a diameter of 60 mm.  The filaments now pass over wire 5, having a diameter of about 2 mm., which is electrically heated, to the draw roller 6 and associated separating roller 7.
